The NLA is up in arms about the proposals and says: “We must make our voices heard so that wannabe MPs realise the strength of public feeling against these damaging proposals.”

The association also claims that landlord support for Labour and the Liberal Democrat Party has halved since the 2010 general election because of their interventionist policies for the private rented sector.

New research shows that landlord support for Labour has fallen from 11 per cent in 2010, to just six per cent who say they intend to vote for the party at next week’s poll.

Landlord support for the Liberal Democrats has also halved – from 10 per cent in 2010 to just five per cent today.

The association has set up a lobbying function on its website to allow members to identify and lobby candidates standing at the election.
